# DESCRIPTION:
|
|
#
|
|
# A thin provisioned volume can become thick provisioned with 'zfs set
|
|
# refreservation=auto'.
|
|
#
|
|
# STRATEGY:
|
|
# 1) Create a sparse value.
|
|
# 2) Use zfs set refreservation=auto to make it thick provisioned.
|
|
# 3) Verify that refreservation is now the size predicted by
|
|
# volsize_to_reservation().
